T0 @Z5 whom, it may concern:

Be it known that we,-JEREMIAH W. DIMicK, Jr.,and JOSEPH JAGGER,citizens ofthe United States, and residents of Rifton, in the county of Ulster and State of NewYork, have invent-- ed a new and useful improvement in Stretchthe same reference character refers to similar parts in the several figures, Figure l is a side elevation of this apparatus. A Fig. 2 is a partial end view of the same.` Fig. 3 isa perspective view showing the frame.-

The table A, preferably `formed with a flat top and with a series of legs A', serves toisupport the removable frame D. At one end ofthis table the movable slide B is mounted so as to move outward in a parallel mannerfrom the adjacent edge of the table A. .This slide is supported upon a series of guides A2, which are rigidly secured to the. tablefand` other guides B2 in the form of round rods are rigidlyv secured to the slide` and passlthrough suitable apertures in the table, so that the slideisaccurately guided in its movements. jA series of screws B3 are mounted in the slide, being held in position with respect .thereto bythe collars B4 and the worm-wheels B5, which are rigidly connected to the screws. The outer ends of these screws engage the threaded nuts B6, which are secured tothe'adjacent edge of the table A. The shaft C,`whi ch is operated by the wheel C, rigidly secured thereto, is mounted in a series of bearingsCf, secured to the slide. This shaft hasV securedto it the worms Cwhich engage theworm-wheels B5, so as to rotate the screws B3 in unison. It will be evident, therefore, that by rotating the wheel C the screws B3 will simultaneously operate and will move `themslidejinia parallel manner with respectto" the table A. The table has secured to its upper surface the retainingledge A3, and, if desired, a number of these ledges may be formed parallel to the edge of the table. The slide has ri gidlysecured thereto aseries of fingers B', which project upfrom the uppersurface ofthe same.

The frame D, formed as is indicated in Fig. 3, consists of side pieces to which are rigidly secured the end pieces .D' D2 and the pressingboards D3, spaced apart at suitable intervals. It is not necessary in all cases to mount the pressing-boards on the frame D, since they may be mounted ,in any desired way, so long as they operate to support the seams of rugs or other articles while these rugs are stretched upon the frame. The strip QE is movably mounted on the end piece D2,.being supported by a series of guide-rods E3, rigid in thestrip and entering suitable holes in the end piece D2.

The series of threaded rods E4 isalso mounted v to revolve in this strip, suitable collars being provided to engage `the inner side of the strip adjacent the end piece D2, and the threaded ends of these rods engage threaded nuts secured to the endpieca D2. These threaded rods are actuated, if "desired, by the removable handles E5, which engage the outer ends of these rods, which are preferably squared. lt will be seen thatL by thisconstruction the strip is free to move at all times away from the end piece D2, but that it cannot move toward the end piece any farther than the collars upon the threaded rods allow. The threaded rods therefore` constitute the holding `means to maintain the stripata distance from` the end piece.of.the extensibleframe. The end piece D'` has pivoted to itthe grip D4,- whichmoves about the fhinges D5, the inner face of this grip being formedwith a series of gripping pins or projections D6 to engage a rug or other material. `This grip may be held down in operative position by a series ofclamps E, which hold the Vgrip in closed position. The strip E has the grip E pivoted to it by the hinges E2, this grip being formed and operating in a similar manner.

In using this apparatusfor the stretching Vof rugs the frame'Displaced upon-.at table, the end piece D' of the frame being in engagement with the retaining-ledge ou themable. The slide is operated so that the fingers B engage the strip Ein the manner indicated in Fig. l. A rug F is then secured to the frame by clamping its edges by means of the grips. The handle C is then operated to force the slide B outward, the fingers B engaging the strip E of the frame, and `thereby stretching the rug in a parallel manner and to any desired extent. Since the seams F are supported by the boards D3, they may be readily pressed while the rugis stretched, and the rug may therefore be given a very smooth appear- The handles E5 may be used to operate the threaded rods E4, so that the collars on these rods engage the strip E. Then if the slide is moved back toward the table by the screws this holding means keeps the strip out and maintains the frame in extended position, so as to keep the rug stretched. The frame and rug may then be readily removed from the table and may be placed in any desired position While'the rug is drying. It will be seen that in this way the rugs are stretched to any desired extent, and after they are stretched they may be stored in this stretched condition upon the light frames, which occupy but little room, While the table, With its heavy mechanism, may be used in connection with other frames. If desired, Ithe table may be formed with a number of ledges A3 to engage frames of'dilerent sizes, and in some instances it is not necessary to employ the stretching mechanism on the table, since the threaded rods may be operated to stretch a rug mounted on the frame.

Itis of course understood that many modi` fications may be made in this invention Without departing from the spirit of the same. Parts of this invention may furthermore be used without employing all of the same, and parts-of this invention may be used in connection with other devices by those skilled in this art. We do not, therefore, wish to be limited to the disclosure which we have made in this case; but what we claim as new and what We desire to secure by Lett-ers Patent is set forth in the appended claims.

We claiml. In stretching apparatus, a table provided with a ledge, a movable slide mounted at one end of said table, screws having worm-wheels secured thereto mounted in said slide to engage said table, a shaft having a series of Worms to engage said worm-wheels, lingers on said slide and a frame to coperate with said table, said frame comprising end pieces and pressing-boards and a strip movably mounted in one of said end pieces, threaded rods in said strip engaging said end piece, a pivoted grip mounted on said strip and provided with pins to clamp material to said strip, a similar pivoted grip secured to the opposite end piece, said frame cooperating with said ledge and said lingers on said table.

2. In stretching apparatus, a table provided with a ledge, a slide mounted in guides at one end of said table, screws provided with Wormwheels mounted in said slide and engaging said table, a shaft mounted in bearings on said slide, Worms on said shaft engaging said worm-Wheels to simultaneously actuate said screws to move said slide in parallel position with said table, an extensible frame comprising pressing-boards, grips to clamp 'material to the ends of said frame and holding means to maintain said frame in extended position.

3. In stretching apparatus, a table, a slide mounted at one end of said table, screws having worm-wheels secured thereto mounted in said slide to cooperate with said table, a shaft. Worms secured to said shaft to engage said worm-Wheels to simultaneously operate said screws and an extensible frame to coperate with said table comprising pressing-boards, grips and 'holding means to maintain said frame in extended position.

4. In stretching apparatus, a table, a slide mounted at one end of said table, means to movesaid slide with respect to said table, an extensible frame provided with grips engaging said slide and said table and pressingboards to support the seams of articles held on said frame. v

5. In stretching apparatus, a frame having end pieces, pressing-boards secured to said frame between said end pieces, a movable strip mounted in one of said end pieces, means to move said strip with respect to said end piece and a grip mounted in said strip.

6. In stretching apparatus, an extensible frame, holding means on said frame to secure an article thereto, means for extending said frame, means to maintain said frame in extended position and pressing-boards to support the seams of said article.

7. In stretching apparatus, an extensible frame to support an article, means to extend said frame and pressing-boards to support the seams of said article.
